Recent advances in pseudomorphic HEMS' (PHEMT) MMIC technology have made it the preferred candidate fo?r high performance millimeter-wave components for phased array applications. This paper will describe the development of V-band PHEMT/MMIC components including power amplifiers and phase shifters. For the single-stage MMIC power amplifier employing a 2(X) 14m PHEMT, we achieved 151.4 mW output power (757.0 mW/mm) with 26.4 % power-added efficiency at 60 GHz. three-stage MMIC amplifier utilizing the same devices demonstrated 80 mW output power, 20.5 % power-added efficiency, and 17 dB associated gain at 57 GHz. And, for the phase shifter, a four-bit phase shifter with less than 8 dB insertion loss from 61 to 63 Olin has been achieved.
